I have seen this. A cybertuck was pulling a small trailer for a landscaping company. It wasn't that interesting because it was a trailer that could have been pulled by most passenger cars, but I saw it.
I will acknowledge this, thought its not exactly what I had in mind.
If Cybertruck marketing claims it to be a truck - I’d like to see it perform in said capacity like a truck would. My F250 tows 8,000 lbs travel trailer as an example. I am yet to see one towed by Cybertruck.
